I've worked with Smart Tags for several years in different projects. Up until now I've always used a VB6.dll to host the recogniser & action interfaces. Never had a problem. Now that I'm using a .Net assembly to do host recognition and actions its works fine for an administrator but I can not get it to load fro a standard user account. I've tried the following:

1. Use HKEY_LOCAL_MACHINE to hold the Office Smart Tag recogniser & action class ids instead of HKEY_CURRENT_USER.

2. Update the CLSID entry under HKEY_CLASSES_ROOT so that the InProcServer entry has the full path name for the mscoree.dll.

3. Updated all of the permissions for addins & macros to allow anything in Office.

4. Add event viewer logging at the entry points for each of the recogniser & actions classes to check whether the process gets that far.

None of the above have helped or been successful. Any advise, or even crazy ideas at this point, would be appreciated.
